A GUI tool that scores your password instantly… and brutally demonstrates why most passwords would not survive 5 minutes against a GPU. Why I Made This During CTFs and security labs, I kept noticing something funny. We spend hours learning: SQL Injection Privilege Escalation Memory corruption Network attacks But in real breaches? Attackers usually log in. Not hack in. They don’t defeat encryption. They defeat human behavior . And the weakest point is always the same thing: passwords. So instead of another terminal script, I wanted something educational. A tool that reacts while you type and visually shows: how a computer actually sees your password. That became PassAudit .
